These are not really the same size class, and that is the honest framing here. The Soundcore Boom 3i ranks #31 of 175 medium speakers by sound quality at $118.99; the Soundcore Boom 2 Plus ranks #37 of 99 boombox speakers by sound quality at $179.99.
The Soundcore Boom 3i is the lighter pick. Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. At 1.7 lbs (783 g) it weighs much less than the Soundcore Boom 2 Plus at 8.4 lbs (3.8 kg). The catch: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close.
The Soundcore Boom 2 Plus is the deeper-bass choice. Quite a bit lighter than most of the other boombox size speakers. Its bass reaches about 39Hz before falling 10dB, against 56Hz for the Soundcore Boom 3i. It keeps a wired aux input, which the Soundcore Boom 3i lacks. It links with other speakers (PartyCast 2.0), which the Soundcore Boom 3i cannot. The catch: Warm tuning meaning a rolled off treble and some upper bass boost.
Buy the Soundcore Boom 3i ($118.99) for a medium speaker; the Soundcore Boom 2 Plus ($179.99) suits a boombox speaker instead.

Pros: Looks to be designed as a direct competitor to the JBL Charge 5 with a very similar sound profile, warm tuned with boosted bass. Better value for the money than the JBL Charge 5. Measured bass extension of 56Hz (-10dB).
Cons: Not quite as good as a JBL Charge 5, doesn’t go quite as loud or sound quite as balanced, but very very close. An earlier firmware version had some bass distortion, update your firmware in the Soundcore App

Soundcore Boom 2 Plus: $179.99 Amazon $179.99 Lowest Soundcore $249.99 eBay
Older model: the Soundcore Motion Boom+ (ranked lower, rated 2.9/5). See every Soundcore Boom generation.
Same family: the Soundcore Boom 2 (smaller model, rated 4.5/5).
Pros: Quite a bit lighter than most of the other boombox size speakers. This speaker will likely move up as we get a good EQ tune that makes it a lot more neutral. Measured bass extension of 39Hz (-10dB).
Cons: Warm tuning meaning a rolled off treble and some upper bass boost. Reasonably deep bass, but not as good as the top ranked.
